I travelled to Bangkok with my friend and this is our first time. The host, Ken is seriously very friendly and helpful. For a first timer, am glad that Ken is around. He showed me the map to go to the MRT and night market nearby. He also has been my translator to the local grabcar and taxi driver as most of them hardly speak English. I just called him and passed the phone to the driver. He is very very very helpful.
As for the room, for a backpackers, Panmanee Apartment is the right place for you. The room got 1 queen / king (not sure) but enough for 2 people. The bed bit hard (maybe because its new!) hehe. Toilet very clean. This apartment located in the local residential area. In the morning, on the way to the mrt, you can see local selling food for breakfast. And its cheap! This is when you can try local food with cheap price. you will find the way is narrow and complicated but dont worry, its a local housing area. Suprisingly, if you just stop taxi nearby the road is much cheaper than grabcar. On my way from airport to Panmanee I took grabcar that cost me 300++ baht. And on my way back to the airport! I just randomly stop taxi by the road, it cost me just 170 baht. Dont worry taxi here they use meter. Pay as per the meter.
